Kumukuai pololei o ka hale hana kaapuni kaapuni o keia manawa

CDADAua hoʻokumu ʻia ma 2004, ʻoiai ʻo ko mākou kumu i hoʻi mai i ka makahiki 1980. Ke kiʻi nei i nā makahiki he nui o ka ʻike loea, ua ulu mākou i mea hana ʻoihana makua a me ka mea hoʻolako o Residual Current Circuit Breakers. Ke kono nei mākou iā ʻoe e hui pū me mākou e pōmaikaʻi mai nā lawelawe kākoʻo ʻenehana hilinaʻi a me ke kumu kūʻai pololei mai ka hale hana.

He aha ke koena o kēia manawa Circuit Breaker (RCCB)?

ʻO RCCB kahi mea hana palekana uila kūikawā i hoʻolālā ʻia no ka wehe ʻana i kahi kaapuni ke ʻike ʻo ia i kahi kaulike ʻole o kēia manawa ma waena o nā mea hoʻokele ola (phase) a me nā mea hoʻokele kū ʻole. ʻO kēia ʻano kaulike ʻole, i ʻike ʻia ʻo koe koe a i ʻole ke au leakage, e hōʻike ana e kahe ana ka uila ma ke ala i manaʻo ʻole ʻia—ma ke kino kanaka a i ʻole ka hoʻohaʻahaʻa kino.

ʻAʻole like me kahiMCBa i ʻoleMCCB, 'a'ole ho'olako 'ia ka RCCB i ka ho'omalu 'ana i ka ukana nui a i 'ole ka pōkole (koe na'e ka hui 'ana me ia ma RCBO). ʻO kāna kumu hoʻokahi ka palekana ola a me ka pale ahi. Hoʻohana ia ma muli o ke Kānāwai o Kirchhoff i kēia manawa, kahi e like ai ka huina o nā au e komo ana i kahi hui me ka huina o nā au e haʻalele ana. Inā ʻokoʻa ke au "in" a me "out" ma mua o ka naʻau o ka hāmeʻa (e laʻa, 30mA), holo ka RCCB.

Nā ʻano a me nā hoʻohālikelike

Hoʻopili kā mākou kōpili hana i nā ʻano RCCB ākea e kūpono i nā kaiapuni uila like ʻole, mai nā hale hoʻokahi-phase a hiki i ka paʻakikī ʻekolu-phase grids.

ʻAno	Pole / Hoʻonohonoho	Nā mea nui	Hoʻohana maʻamau
ʻAno AC	2-Pole (1P+N) / 4-Pole (3P+N)	ʻIke i ke koena AC sinusoidal.	ʻO nā hale noho a me nā kukui uila / kaapuni mana.
ʻAno A	2-Pole / 4-Pole	ʻIke i ka AC a me ka pulsating DC koena au.	Nā kaapuni me nā ukana uila (nā mīkini holoi, kamepiula, dimmers).
ʻAno F	2-Pole / 4-Pole	E ʻike i ka AC, DC pulsating, a me nā ʻauwaʻa multi-frequency composite.	Nā kaapuni kūikawā me nā kaʻa holo wikiwiki (VSD) a me nā mea hana papa I.
ʻAno B	4-Pole	ʻIke i nā ʻano ʻano A/F a pau me nā ʻaukaha koena DC maʻemaʻe.	ʻEkolu mau kikowaena EV charging station, solar inverters, a me nā mea lapaʻau.

Nā hana kumu a me ka pale naʻauao

ʻO ka puʻuwai o kā mākou RCCB ʻo ka Zero-Sequence Current Transformer (Toroid). Ke nānā mau nei kēia ʻāpana i ke kahua magnetic i hana ʻia e ke kahe o kēia manawa.

ʻIke Leakage: Ma lalo o nā kūlana maʻamau, hoʻopau nā mākia magnetic o ke au Live a me Neutral kekahi i kekahi. Inā loaʻa kahi ala leaka i ka honua (e laʻa, hoʻopā ke kanaka i kahi uea ola), ua haki ke koena.

Hoʻokuʻu wikiwiki: ʻIke ka mea hoʻololi i kēia kahe "koe" a hoʻoulu i kahi voli i kāna wili lua. Hoʻonui ʻia kēia hōʻailona (ma nā ʻano uila) a i ʻole e hoʻokō pololei i kahi relay koʻikoʻi (ma nā ʻano electromagnetic), e hoʻokuʻu a wehe i nā mea pili.

Nā helu hoʻonaʻauao:

ʻIke Kiʻekiʻe (10mA - 30mA): No ka pale pili pono (palekana kanaka). Pono no nā lumi ʻauʻau, nā kumu, a me nā kaapuni waho.

ʻO ka ʻoluʻolu (100mA - 300mA): No ka pale ʻana i ka pilina pili ʻole a me ka pale ʻana i ke ahi. Hoʻohana ʻia i nā papa hoʻolaha nui e pale i nā kaula mai nā hewa insulation.

Nā noi mua a me nā hihia hoʻohana

Palekana hale: Pono e hoʻokomo i loko o nā lumi ʻauʻau, lumi kuke, a me nā puka waho e pale ai i nā haʻalulu make mai nā mea hana e like me nā mea holoi lauoho a i ʻole nā mea hana mana.

Mekini Hana Hana: Ka pale ʻana i nā mea hoʻohana mai ka haʻalulu uila i ka wā e lawelawe ana i nā mea hana metala a i ʻole nā mea lawe lima.

Nā mea mālama ola: Ka hōʻoia ʻana i ka palekana o ka poʻe maʻi i nā halemai kahi e hiki ai i nā wai leaka liʻiliʻi ke make (e hoʻohana ana i ka Type B a i ʻole nā ʻōnaehana IT olakino kūikawā).

Hiki ke hoʻololi i ka ikehu: Ka pale ʻana i nā ʻaoʻao DC a me AC o nā ʻōnaehana PV solar a me nā kikowaena EV mai nā hewa ʻāina.

Hana Pono: Mai Mea Maka a i Huahana Pa'a

ʻO kā mākou kaʻina hana he symphony o nā magnetic precision a me ka ʻenehana mechanical.

1. Nā Mea Makaʻu Nui:

Koko Transformer Kaulana Zero: Hana ʻia mai ka Permalloy (Nickel-Iron alloy) a i ʻole Nanocrystalline. He mea koʻikoʻi kēia mea no ka ʻike ʻana i nā au leakage minuke me ka saturation.

Kaahele Kaahele/Solenoid: He relay polarized koʻikoʻi e hoʻololi i ka hōʻailona uila mai ka mea hoʻololi i ka neʻe ʻana.

Hale noho: Polycarbonate (PC) a i ʻole Nylon (PA66), i hoʻolālā ʻia no ka hoʻoheheʻe ʻole a me ka pale ʻana i ka hopena.

Hoʻopili: Silver-Cadmium-Oxide (AgCdO) a Silver-Nickel (AgNi) no ka hoʻololi pono ʻana a me ke kūpaʻa haʻahaʻa.

2. Ka Hana Hana Hana Hana:

Ka makani Toroida: Ua ʻeha ʻia ke kumu hoʻololi pololei me nā tausani o ka huli ʻana o ka uea keleawe maikaʻi loa. Pono e hana ʻia kēia me ka mālama nui e pale aku i ka pōkole o nā huli.

Hoʻopaʻa paʻa: Hoʻopili ʻia ke kumu magnetic i loko o ka resin epoxy e pale iā ia mai ka haʻalulu a me ka haʻahaʻa, e hōʻoia ana i ka paʻa lōʻihi.

Ahahui: Hoʻonoho ʻia ka toroid a puni ke ala alakaʻi (a i ʻole e hele nā mea hoʻokele ma ia). Hoʻopili ʻia ka mīkini huakaʻi i ka latch pili nui.

Hoʻoponopono ʻia: ʻO kēia ka hana koʻikoʻi loa. Hoʻohana mākou i nā kumu kūpono o kēia manawa e hoʻokomo i kahi leakage (e laʻa, 30mA). Hoʻoponopono ʻia ka huila huakaʻi a hiki i ka hoʻā ʻana ma ka paepae.

Ka Mana Koʻikoʻi a me nā Kūlana Hoʻāʻo

Hoʻopili mākou i nā kūlana IEC/EN 62423 a me IEC/EN 61008. Hoʻolālā ʻia kā mākou ʻōnaehana hoʻāʻo e hōʻoia i ka hele ʻana o ka hāmeʻa i ka wā e pono ai, a i nā manawa a pau e pono ai.

Nā mea ho'āʻo maʻamau a me nā koina nānā hale hana:

Mea hoao	Kuhikuhi maʻamau	ʻO kā mākou hale hana maʻamau a me ke ʻano
Ka huakaʻi o kēia manawa	Hōʻoia i ka ʻike (IΔn).	Hoʻokomo i kēia manawa ma 1.0 x IΔn (pono e hele <300ms) a 0.5 x IΔn (ʻAʻole pono e hele).
Hoʻokolo manawa	Hōʻoia i ka wikiwiki o ka hana.	Inject 5 x IΔn (e.g., 150mA). Pono e holo ka mea hana ma < 40ms (General Type) a i ʻole i loko o ka manawa i koho ʻia no Type S (Selective).
Ka ikaika dielectric	Hōʻoia i ke kaʻawale.	Hoʻohana ʻia 2000V AC no 1 minuke ma waena o nā pahu hoʻokomo/puka a me ke kiʻi. ʻAʻohe haki.
Hana Mechanical	Hōʻoia i ka lōʻihi o ka latch.	2,000 pōʻaiapuni o ON/OFF hana me ka hāʻule ʻole.
Kaapuni Pokole ke ku	Hōʻoia i ka hiki ke ola.	Pono ka RCCB e kū i kahi au o ka pōkole (e laʻa, 3kA a i ʻole 6kA) me ka ʻole o ka pahū ʻana a i ʻole ke ahi (hōʻoia ʻia e ka pale fuse).

ʻO kā mākou Hana Hana: Laina, Lako, a me ka Hui

Hoʻolako ʻia kā mākou hale hana no ka mālama ʻana i ke ʻano palupalu o nā ʻāpana ʻike magnetic.

Laina Hana Hana: Hoʻohana mākou i nā mīkini wili toroidal e hōʻoia i ka helu huli ʻana a me ka haʻalulu, he mea nui ia no ka ʻike pololei ʻana i kēia manawa.

Mea Hana Kiʻekiʻe:

ʻO nā Calibrators Leakage o kēia manawa: ʻO nā mea hana pono kiʻekiʻe e hiki ai ke hoʻohua i nā au leakage me ka hoʻonā ʻana o 0.1mA no ka hoʻonohonoho pono ʻana i ka huakaʻi.

Keena Palekana Magnetic: Hoʻohana ʻia i ka wā e hui ai no ka pale ʻana i nā māla magnetic waho mai ke keʻakeʻa ʻana i ke kaʻina hana calibration maʻalahi.

Na Papa Hoao Aunoa: 100% o nā ʻāpana e hoʻāʻo ʻia ma mua o ka hoʻopaʻa ʻana.

Hui Pūʻali:

ʻEnekinia Magnetic: He poʻe loea i ka hoʻolālā ʻana i ka geometry o ka transformer zero-sequence e hoʻonui i ka naʻau.

Nā ʻenehana hoʻolāʻau: Nā limahana i hoʻomaʻamaʻa nui ʻia e hōʻoia lima lima i nā paepae huakaʻi o nā kumu hoʻohālike.

Hōʻoia maikaʻi: Hoʻolaʻa ʻia i ka nānā ʻana i nā ʻano hana hemahema a me ka hōʻoia ʻana i ka hilinaʻi o ka mīkini huakaʻi.

E koho i kā mākou Koe Kaapuni Kaapuni o kēia manawa. ʻAʻole mākou hana wale i nā hoʻololi; ʻenehana mākou i ka maluhia o ka noʻonoʻo mai ka ʻike ʻana i kāu kaapuni ke nānā nei i kou kua.
